gear shifting problems, '18 DL650
I'm a bit over 1000 miles on my bike. My first oil change at less than 200 miles was to Mobil 1 4T 10/40. After a few hundred miles more, shifting was feeling notchy, maybe a little gritty. There was nothing smooth about the process. As time went on, on occasion downshifting would give a false neutral between each gear when trying to do multi-down clicks on one clutch lever pull. I'd pull the lever and down shift, and a second toe tap to go down one more resulted in a false neutral, I'd have to partially release the lever, hear and feel the transmission engage that lower gear, pull the lever back in, down shift again, try for 2 toe-taps on 1 lever pull, only get one down shift, then partially release the lever and feel the next lower gear engage... over and over from whatever upper gear I was in. This behavior is sporadic but happened maybe a few times with each trip.
This spring start-up, nearing 1000, I drained the Mobil 1 and put in Amsoil 10/40 motorcycle oil and a fresh filter. Much improvement, until after just a couple hundred miles the behavior has started again. Notchy and gritty gearing up or down, and sporadic episodes of false neutrals between down shifts. (When this happens, it happens through the entire down shift range, from whatever gear I am in all the way to 1st.)
My engine oil level is full (not over-full), the clutch lever is adjusted according to the owner's manual and the Dr. VStrom video, and the cable action feels good. I can confirm freeplay at both ends of the cable, but it sure is feeling like the adjustment needed is beyond a cable adjustment. Am I looking at service inside the clutch or transmission?
I'm a gentle 50-year old rider- no speed shifting, no clutch-less shifting, no "shifting to 7th gear" occurrences.
